New inverter generators designed for AC TIG aluminium welding and DC TIG welding for steel. HF (high frequency) or Lift-Arc ignition feature. MMA mode also available. Thanks to the inverter technology and microprocessors, the welding process is controlled at all times, guaranteeing excellent welding dynamics and optimal arc ignition. The new COMPACT EVO AC / DC series is equipped with a simple and intuitive control panel. Thanks to the touchscreen technology, welding parameters can be set quickly and easily. It is however possible to set the machine using the two knobs on the panel. 3 user interface modes: Basic, Intermediate and Advanced. Possibility to memorize up to 99 programs. In TIG mode the following functions are available: • Slope up (from 0 to 10 seconds), Slope down (from 0 to 10 seconds), pre-gas (from 0 to 25 seconds) and post-gas (from 0 to 25 seconds) • synergic post-gas • possibility to set the initial and final current time • base current, current 2, initial and final current both in absolute value and in percentage with respect to the main current • PULSED TIG ideal for welding on thin thicknesses (frequency adjustable from 0.1 to 5000 Hz), with adjustment of base and peak current and duty cycle throughout the frequency range. • AC process with rounded square wave to reduce arc noise while preserving welding quality • TIG MIX AC function, which allows you to alternate between AC time and DC time • ‘TACK’ function, which allows joining two flaps with high penetration, speed and precision As for the MMA mode, the adjustable parameters are the Hot Start and the Arc Force. There is also the VRD function required for use in high-risk environments. Possibility of remote adjustment by manual controls, by foot pedal or by Tig up-down torch.
